ULTRA: Unified Multimodal Control for Autonomous Humanoid Whole-Body Loco-Manipulation

ULTRA is a unified framework for autonomous humanoid whole-body locomotion and manipulation that overcomes limitations of prior methods by combining a physics-driven neural retargeting algorithm with a multimodal controller. The retargeting algorithm translates large-scale motion capture data into physically plausible humanoid motions, while the controller learns to handle both dense motion references and sparse task specifications using a range of sensory inputs, from accurate motion-capture states to noisy egocentric vision. In simulation and on a real Unitree G1 humanoid, ULTRA demonstrates improved generalization and robustness, enabling coordinated whole-body behavior from sparse intent without relying on test-time reference motions.

ViT-H: Generative Video-To-Humanoid Control with Motion Tracking Feedback

ViT-H is a video‑to‑humanoid control framework that generates humanoid reference motions directly from monocular human videos using a diffusion model, eliminating the need for separate reconstruction, retargeting, and tracking stages. The system incorporates motion‑tracking feedback to fine‑tune the generator via preference optimization, and an autoregressive variant enables real‑time teleoperation with sub‑400 ms latency. Experiments on the Unitree G1 robot show that ViT‑H surpasses existing reconstruction‑retargeting‑tracking pipelines in motion quality and executability, and its performance scales positively with model size and data volume.
